I would expect a few more systems to arrive in the next few months, as smart phone adoption reaches a more "critical mass".
I would expect a 'Software as a Service' or a "cloud based" offering for small and midsize independent forklift dealers and service companies that would do most everything a program like Minitrac or NDS does now, but do it without the redundant data reporting of one person entering it on paper to have anther enter it in data so a 3rd person can print a paper report.
If any one is interested in helping by being a "crash tester/ bug reporter/early adopter" please contact me via e-mail.
